I have written equations of a holographic dark energy model with interaction in CAMB. (w_de rho_de which are ODE and must be solved numerically).
I have tested the CAMB with simple code and it printed list of numbers so fast and plotted it using Gnuplot.
But, as I replace the equations with my model, CAMB takes more than 10 hours to print just half of that list while saying rombint failed to converge...
I do not know how should I do, the equation I wrote for my model is ODE which works properly. I use RungeKutta 45 for solving that (w_de)
